Description
Technical field
The utility model relates to a kind of valve, specifically a kind of sealing configuration of valve.
Background technique
There is certain defect in existing valvular sealing configuration: valve in use between in process seal ring can wear and tear gradually, the sealing effect that causes valve worse and worse and ultimate failure, has affected the normal use of valve; As in adopting the valve of O RunddichtringO, the inner hole part of O RunddichtringO that can wear and tear when stem movement is frequent, causes leakage thereby make to produce gap between valve rod and seal ring in stem position.
To this, researcher has made architecture advances, and V-shaped seal ring gap to sealed member under the cooperation of spring self-compensation sealed structure is compensated, and also can keep good sealing effect at ring wear after to a certain degree; But, this structure relative complex, manufacture processing cost is higher, and between gland and valve gap, adopt common metallic gasket, the inner peripheral surface of valve gap still exists certain leakage hidden danger, and (V-shaped seal ring is positioned in gland, can only guarantee the sealability of valve rod outer peripheral surface), still need and further improve.
Model utility content
The purpose of this utility model is the deficiency overcoming in above-mentioned background technology, and a kind of bowl type sealing configuration of valve is provided, and this bowl of type sealing configuration should have good sealing effect, simple in structure, easily manufactured feature.
The technical solution of the utility model is: a kind of bowl type sealing configuration of valve, comprises valve body, can be arranged in valve rod in valve body positioning hole vertical motion, is arranged on the nail pressing at valve body positioning hole top; It is characterized in that: on described valve rod, wearing respectively a bowl RunddichtringO, be positioned at bowl upper and lower two ends of RunddichtringO two O type black boies, be positioned at nail pressing and by O type black box, carry out the spring of extrusion bowl RunddichtringO.
Described bowl RunddichtringO adopts teflon to make.
Described O type black box comprises aluminium pad, be arranged on aluminium pad inner peripheral surface and compress valve rod outer circumferential face inner seal ring, be arranged on aluminium pad outer peripheral surface and compress the exterior seal ring of valve body positioning hole inner peripheral surface.
On the inside and outside circle side face of described aluminium pad, be manufactured with respectively a circular groove, inner seal ring is arranged in the circular groove of aluminium pad inner peripheral surface and exterior seal ring is arranged in the circular groove of aluminium pad outer peripheral surface.
The beneficial effects of the utility model are:
Between valve rod of the present utility model and valve body, by bowl RunddichtringO and two O type black boies, seal, and play elastic compensating effect by spring-compressed bowl RunddichtringO, can remain good sealing effect; Therefore, the utility model not only has the feature of reliable in quality, good sealing effect, long service life, and structure is comparatively simple, and comparision of production is convenient, and manufacture cost is also lower.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, a bowl type sealing configuration for valve, comprise valve body 1, be arranged on valve body positioning hole 11 tops nail pressing 3 (bear down on one with valve body positioning hole between be connected by worm structure 12), pass through nail pressing and can be arranged in valve rod 2 in valve body positioning hole vertical motion, be positioned at spring 5, O type black box 6 and bowl RunddichtringO 4 in this positioning hole.
In described O type black box, on the inside and outside circle side face of aluminium pad 61, be manufactured with respectively a circular groove, inner seal ring 62 is arranged in the circular groove of aluminium pad inner peripheral surface and compresses valve rod outer circumferential face, and exterior seal ring 63 is arranged in the circular groove of aluminium pad outer peripheral surface and compresses valve body positioning hole inner peripheral surface; Described O type black box is arranged in the two ends up and down of bowl RunddichtringO, comprises the lower seal assembly that is positioned at the upper black box of bowl RunddichtringO upper end and is positioned at bowl RunddichtringO lower end.
The axial section of described bowl RunddichtringO is V-arrangement and generally adopts teflon to make; As shown in FIG., the opening upwards of bowl RunddichtringO is arranged (also can arrange) downwards.
Described spring (being positioned in nail pressing), upper black box, bowl RunddichtringO, lower seal assembly (being located at positioning hole end face 13 tops) are set on valve rod from top to bottom successively, therefore on the inner peripheral surface of valve body positioning hole and the outer peripheral surface of valve rod, all by two O type black boies and bowl RunddichtringO, seal, possess good sealing effect;
Simultaneously, described nail pressing holddown spring makes spring apply downward pressure to upper black box, therefore there is deformation and have the trend stretching in the horizontal direction in bowl RunddichtringO under the extruding of upper black box and lower seal assembly, and the inner peripheral surface of bowl RunddichtringO and outer peripheral surface are pressed on respectively on valve rod outer peripheral surface and positioning hole inner peripheral surface; When there are wearing and tearing in the inner peripheral surface of bowl RunddichtringO, at the spring lower bowl RunddichtringO of exerting pressure, there is further deformation (compensating by elasticity), the inner peripheral surface of bowl RunddichtringO continues to be pressed on valve rod outer circumferential face, has guaranteed the reliability sealing;
The utility model is in when assembling, if successively by lower seal assembly, bowl RunddichtringO, upper black box, spring is set on valve rod and tighten nail pressing, just can complete assembling; While dismantling with maintenance, as long as turn on nail pressing, more just can take out a bowl RunddichtringO after taking out spring and upper black box, very convenient.
